| الوصف: | Our ability to interact with the world depends on memory buffers that flexibly store and process information for short periods of time. Current working memory research, however, mainly uses tasks that avoid eye movements, whereas in daily life we need to remember information across saccades. Because saccades disrupt perception and attention, the brain might use special transsaccadic memory systems. Therefore, to compare working memory systems between and across saccades, the current study devised transsaccadic memory tasks that evaluated the influence of memory load on several kinds of systematic and unsystematic spatial errors, and tested whether these measures predicted performance in more established working memory paradigms. Experiment 1 used a line intersection task that had people integrate lines shown before and after saccades, and it administered a 2-back task. Experiments 2 and 3 asked people to point at one of several locations within a memory array flashed before an eye movement, and we tested change detection and 2-back performance. We found that unsystematic transsaccadic errors increased with memory load and were correlated with 2-back performance. Systematic errors produced similar results, although effects varied as a function of the geometric layout of the memory arrays. Surprisingly, transsaccadic errors did not predict change detection performance despite the latter being a widely accepted measure of working memory capacity. Our results suggest that working memory systems between and across saccades share, in part, similar neural resources. Nevertheless, our data highlight the importance of investigating working memory across saccades. |
